Kewl Tune Deck #772729 — Yu-Gi-Oh! OCG

Deck — Deck Power Evaluation

Final Contextual Deck Power: 30/100 (±10 · Confidence: Low)

• Primary strategy: Combo
• Secondary strategies: Toolbox
• Format: ocg

Legality

Main 40 / Extra 15 / Side 0 — status under the rules at evaluation time: Illegal. 4 violation(s).

Identity & game plan

• Win condition: Synchro Summon Kewl Tune Extra Deck monsters (Chaos Angel, Super Starslayer TY-PHON, Kewl Tune B2B) off a Tuner-heavy opening; Kewl Tune B2B second attack and Kewl Tune Loudness War board presence
• Turn 1 (going first): Normal Summon a Kewl Tune Tuner, use Kewl Tune Mix/Reco/Cue search and Kewl Tune Synchro to reach a Synchro Summon (Inferred from card text; no recorded boards)
• Turn 2 (going second): Hold Ash Blossom, Infinite Impermanence, Effect Veiler and Ghost Ogre as hand traps to break the opponent's first engine, then rebuild through Kewl Tune searchers (Inferred)
• Recovery: Recur Tuners from the GY via Kewl Tune Mix/Reco/Clip and Kewl Tune Playlist, then re-Synchro (Inferred)
• After siding: Not evaluable: the deck runs no Side Deck (side_count 0)

Why it scores here

The deck is Illegal as built: it runs three copies each of Kewl Tune Cue, Kewl Tune Synchro and Kewl Tune Reco against a limit of one, and three Ash Blossom against a limit of two, so under the rubric it is capped and scored as theoretical or structural only. Its structural read rests on a dense Tuner engine: P(at least one archetype core card in an opening 5) is about 0.88 and 14 searcher-text cards support consistency, which is Inferred from the hypergeometric estimates. Interaction is the deck's strongest system feature, with 13 hand-trap and 13 negation-text cards and about 92% chance of a hand trap in a going-second 6, which earns the going-second and interaction dimensions. No recorded boards, combo medians or matchup data exist, so the combo floor and matchup dimensions are low-confidence estimates rather than measured output. The score was not built by averaging card scores, and the Kewl Tune archetype's popularity was not credited as power; the deck has no side deck and no post-side plan, which holds back adaptability.

Dimension scores

How the score was computed

Strategy profile: Combo primary; Toolbox secondary, disclosed but not blended numerically. Structural ≈ 51, Going First ≈ 48, Going Second ≈ 52, Meta = provisional, Tournament Reliability ≈ 40. Modifiers: banlist exposure (-12). Final formula: No reliable metagame: 0.80*Structural(51) + 0.20*TournamentReliability(40) + Modifiers(-12) = 37; Illegal cap applied, final score set to 30 (theoretical/structural only)

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.88 · key two-card combo ≈ — · full-brick estimate ≈ — (all Inferred)
• Combo output: best PowerIndex —, median —, board-per-starter —
• Turn order: 0 going-first lines vs 0 going-second lines

Strengths

• Dense Tuner engine with about 88% chance of an archetype core card in opening 5 (Inferred)
• Layered hand-trap and negation coverage, including about 92% chance of a hand trap going second (Inferred)
• Strong Synchro closers in Chaos Angel, Super Starslayer TY-PHON and Kewl Tune B2B (verified stats)

Weaknesses

• Illegal copy counts: three Limited cards run at 3 copies against a limit of 1
• No side deck, so no post-side adaptability
• Only 47% exact-name archetype purity; 19 generic cards dilute the engine
• No recorded boards, so combo floor and median are unmeasured

Critical choke points

• Kewl Tune Synchro and Kewl Tune Mix as the main searchers into Synchro lines
• Once-per-turn Tuner recursion depends on a limited number of Tuners in the GY

Recommended changes

Evidence & confidence

• Verified: Illegal status: copy-limit violations for Ash Blossom, Kewl Tune Cue, Kewl Tune Synchro and Kewl Tune Reco; Main 40 / Extra 15 / Side 0 within OCG size rules; Card stats and card text excerpts for all listed cards; Archetype purity 47.3% and archetype spread
• Inferred: Opening-hand consistency about 0.88 for an archetype core card; Going-second hand-trap probability about 0.92; Primary strategy Combo with Toolbox secondary; Interaction quality read from card text
• Provisional: Meta power and matchup fit (no dated metagame sample); Combo floor and median (no recorded boards)
• Data gaps: No combos supplied; combo floor, median and ceiling are text-only inference No tournament link; archetype meta share and per-pilot record absent No win-rate telemetry for going-first, going-second or matchups Meta power is provisional without a dated metagame sample Deck has no side deck, so post-side performance cannot be assessed
